WATE-B-LIFTING DEVICE.

Specification of Letters Patent.

Patented Mar. 30, 1915.

Application filed December 5, 1913. Serial No. 804,956.

To all whom it may concern:

Be it known that I, BERNHARD MUHsoLD, a citizen of the United States, residing at WVashington, District of Columbia, have invented new and useful Improvements in ater-Lifting Devices, of which the following is a specification.

This invention relates to Water lifting devices.

One object of the invention is to provide a water lifting device embodying among other characteristics means whereby the water of city or other mains may be lifted to elevations higher than the normal pressure is calculated to force it.

Another object of the invention is to provide a water lifting device particularly adapted for connection in pipe lines of dwellings or other high buildings so that water may be readily supplied to the uppermost floors when the normal pressure is not suflicient to force the water to the upper floors.

A still further object is to provide a Water lifting device designed to lift water and it may be operated either by connection with city water mains or by location in streams, race-ways or other bodies of water.

With the above and other objects in view the present invention consists in the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings and particularly pointed out in the appended claims, it being understood that changes may be made in the form, proportions, size and minor details without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings :Figure 1 is an elevation, partly in section, Fig. 2 is a vertical sectional view, Fig. 3 is a horizontal sectional view on the line 0ew of Fig. 1, Fig. 4: is a top plan view, Fig. 5 is a cross-sectional view of one of the tank valves, illustrating the parts thereof in closed relation. Fig. 6 is a detail view of the inner tubular member of one of the tank valves.

Referring now more particularly to the accompanying drawings, the reference character 10 indicates a tank of any suitable material and capacity. In its side wall it has openings in which are mounted inlet and outlet valves A and B, respectively. These valves may be of any suitable character, but,

as shown, each valve consists preferably of an outer tubular member 11 fixed in the respective opening in the tank with a tubular member 13 fitted therein. Said outer mem bers 11 are open at their inner ends and each has a plurality of port openings 12. Each tubular member 13 extends into the tank and has its inner end open and notched to form shoulders 13 and 13 and each has ports 14 adapted to be turned into and out of registration with the ports 12 of the outer tubular members so as to open and close the valves for a purpose presently explained. Casings 15 and 16 are fitted over the valves A and B, respectively, and each has a nipple 17, by virtue of which, the valve A may be connected to a water supply pipe (not shown) of a building While the valve B may be'connected to a drain pipe (not shown), all for a purpose presently explained.

Slidably mounted in the tank 10 is a water chamber 18 which is preferably cylindrical and which is preferably fitted in a rectangular shaped jacket 19 and secured thereto so that both move vertically together. The jacket 19 not only shields the water chamber 18 but provides interspaces which form air chambers 20 between the chamber 18 and the acket 19 to render the water chamber buoyant. Arranged centrally in the bottoms of the chamber 18 and jacket 19 is a hollow bushing 21 which forms a seat for the valve 22. There may be a plurality of these bushings 21 and valves 22, if desired.

The water chamber 18 and its jacket 19 are preferably open at their upper ends and are movable vertically in guides 23 under the influence of pressure of water in the tank 10 resting in lowermost position on the shoulders 58 adjacent the bottom of the tank 10, as will be explained. The guides 23 are preferably of the angle iron type to eifectively slidably receive the angular corners of the jacket 19 and may be braced by the brackets 24, if desired.

Supported on the tank 10 in any suitable manner is a frame consisting of uprights 25 and cross-pieces 26. Depending from the cross-pieces 26 of the frame are arms 27 adapted to fixedly support a piston 28, which the water chamber 18 is adapted to slidably embrace, there being suitable packing material 29 carried by the piston to prevent the passage of air into the water chamber. As indicated at 30 Water may be used W to ,eife'ctually ,seal the joint between the piston and chamber and therebyflexclude air from the chamber. Arranged preferably centrally ton'30 is an opening adaptedeto receive a 'hollow bushing 31 which has a valve seat "for a valve 32. To the ;outer end; of this i "bushing. 31 may be connected a section33 of the Water pipe line of a building. Aplurality of bushings "31 and valves 32 may be employedgif desired so asto connect the wat'e r chamber up" with aiplurality of outlet pipes or .conduits for thesp'urpose of directing water to 'difierent points. Thus my device is readily applica'ble for'disposi-. tion in the :water pipeline leading from a 7 "city main into a building for the-purpose of lifting water to theuppe'r' floors of a tall.

3 "buildingias will be explained.

v movement of the water chamber andito this s end suitable connections beemployed to operate the valves, If'desired, the inner Y "tubular members'13 of each ofthe valves A f and'B may h'aveat itsinner end ai'web- 34 V The valves A and B are controlled bythe provided with a stud 35. These studs fit in brackets 36" in each of whichflatter a screw I i "the other'jof said shoulders 13 and13 "at 37 may be mounted for engagement' with' the corresponding stud to take'up unduelooseness in the inner tubular1member13'of the respective valves. Levers 38 and 39 are journaled' on said studs 35' and are movable in the notch at the innerend of the respecs tive'innertubular part of the valves A and {B for engagement first. with one and then the ends of the notches. On each lever 38 and 39 is adjustably mounted .a Weight 40.

FEach weighted lever 38 and 39v has, a dog 41 and 42,"='respectively', pivoted thereto adaptt ed to co'operatewith upper and lowerpairs of shoes, the upper set including two shoes 7 43 and 44 and'the lowersetincludingtwo Yshoes'45 and 46. V

The shoes 43,44; 45 46 each has a recess '47 and are freely -slidable on guide 1 strips48 and "49 arranged between the jacket '19 and'thetank lOfand preferably supported from the latter by connections 50 and 50.

nected to the shoes45 and 46 are chains-53 V andf54,-respectively. Each of these chains a the pie conn'e'cted to thedshoes '43 p and 44 are chains'5l and 52, respectively, while con- .tion on the shoulders 58 adia c'ent'the bot .tom..of the tank 10. The valve A is now .opento letsin watenintouthegtank. When the valven reopen the operating lever 38 occupieskthe full line position shown in Fig. l with its dog 41 engaging the shoe 44; At this time the valv'e B is closed with the operating lever 39 occupying full" line position shown--in'-*'-Fig.1, with its dog 42 engaging the shoe '45. Thewater,graduallvrises p in the tank 31 0 and lifts the "water chamber 18j;forc ingwater of thefchamber into the sup'plypipe or conduit 33. The chains 52 1211111753 connected to'the shoes '44 and 45 and f'tof thB'jaCkGt lQQf the chamber "18' gradually 8o becometaut" just before theywater chamber 18 reaches its uppermostpositionsand pull the shoes 44 'and 45 upwardlyon the guide strips 48 and 49. This action causes the H levers 3'8 and 39 tofbe drawn away from the 1 shoes 44 aI-id'45j to slightly -past'dea'd center of perpendicular positionfofflthe leversinto 1 engagement with the respective shoulders 13* and 13 ofgthe respective sinner members V of the valves A and B; when the weights40 0" on the; levers will cause the levers to rotate the inner valvelmembers l3 and'to' assumej the dotted line positions shown in Fig {1, 7 V "fis rs 6 14 and, 45 lowering slightly incij jdent to the slackening ofthe chains '51 andp theleveri' 38 is thereby shifted the shoe 44 to the vshoe 4'3 thevalve Aisfclosed i and as theflever 39 is.shifted"simultaneously A fwith the lever 38'fr om the shoe45'to the shoe-" 46', the? valve A isclosed and the valve. TB opens with the 'result that 1the-inlettvalve A is. closed and the water'inthejtan k drains s out throughthe valve Bfandfthewvater"cham I ber 18 falls -with the "lowering of" the water in" the tank. As the chamberrl8 lowers,'the

'pressure on the" water in'the tank 10 lifts the valve 22 and water isithereby=takeninto the chamber 18to replenish the same with water ;or, give to thefchamber an'amount ofwater 11; substantially "the same in quantity as that discharged intothe pipe 33fon the upstroke of the chamber 18. When the water chamber reaches "its lowermost position in the tank, the'lever 39 isthr'ownby'the shoe .46 11 to the fullline positionin Fig. lto close the outlet oridrain' valve 13 while the shoe 43 "throws'the lever 38 13013116 e111 line position in-Fig. l to repeatithe' operation and thereby,

lift the water forpurposes herein explained;

It will thus be seen'that the'valveslA and B open. andiclose alternatelyjunder the in- T fiuence of the movements of the water chamber and Ijwi'sh' it to be understood that I4,

may eliminate the tank 10 and position thel25- water'chamber for operation under the influence of rising and falling tides.

My water lifting device is equally appli cable for thepurpose of lifting water for, power purposes and for use in irrigating 13o systems as it is for connection in the line of water supply pipes for buildings. Furthermore, the device may be readily substituted for the pumps now used for boiler injection and will effectually feed water under high pressure to boilers.
